Re: Malaysia Airlines Flight Vanishes

I feel the worst for the families, who seem to be a very long way away from having any closure.
Imagine not knowing the fate of your loved ones.

Tragic.

Doppler effect use to determine the plane had taken the Southern route. Thus the announcement today.
Interesting analysis and confirmed by checking against a known source. Good work, it seems.
The company then compared its theoretical flight path with data received from Boeing 777s it knew had flown the same route, he said, and it matched exactly.
Now, my only question on this data is... What other 777's fly that particular route into the abyss of the Southern Ocean?
I fly over the North Pole frequently, when heading to Asia. Is a South Pole route typical from anywhere in the Pacific? :confused5

ETA: Answer seems to be yes... http://www.airliners.net/aviation-forum ... n/2372669/" onclick="window.open(this.href);return false;
JHB to SYD would probably provide good data for comparison.

Malaysia Airlines Flight 370 went down over the southern Indian Ocean, Malaysian Prime Minister Najib Razak said Monday, citing a new analysis of satellite data by a British satellite company and accident investigators.
The investigation seems to be narrowing... Still, nobody's put a hand on any debris confirmed to be from that flight.

If you were taken hostage by hijacking and flown somewhere in the back of a plane, could you tell your loved ones where you are? Provided your phone wasn't discovered and taken in the first place I mean.
Yes... Within a few feet anywhere in the world... My phone has GPS
Provided you had cell coverage to call. A GPS does you no good without the capability of making contact. There is not cell coverage in many large areas of the world. Even the US has LOTS of areas that have limited to no cellular service.
Agreed.. Knowing where you are but not being able to tell anyone isn't very helpful.
However, I'd wager that anywhere that had a runway lng enough to land a 777 is close enough to a tower to make a call.
No so for a dirt landing in a remote desert, or a Siberian 4-lane.

If ocean currents average ~3kts and debris is discovered 14 days after the crash, that's 3 x 24 x 14 = 1,008 Nautical miles = 1,160 statute miles.

I've been watching the news for too long. Something about 199' 11" stuck in my head.
Watching that stat on the news graphics I keep thinking.... "Sooooo close, you'd think they'd have found a way to add another inch"
Maybe the 200' mark pushes them into a different insurance coverage bracket. ;)

Serious question...does anyone know how they were able to find the Air France plane's black boxes 2 years after that one crashed off the coast of Brazil (I think it was Brazil?)? I keep hearing that the pings only last for 30 days...did they juist get lucky with the Air France plane to find them after so long? I realize they at least had an idea of where to look for those.

Still seems like a needle in a haystack for that too.
Without looking it up, IIRC, they at least had a debris field to use as a starting place. They had only a short time between the last known transponder position and the crash location. So, they knew the location of the AF crash within some reasonable surface area. In the Malaysia case, there's not a shred of debris located so far and the area of possibility is a circle that encompasses a surface area roughly 6 times the size of the USA. Yes, they are doing things to narrow that down, but, it sure seems like educated guessing, rather than any certainty.

Trying to figure out what part of the plane would still be afloat that would measure 80 feet. According to the experts about the only part of the structure that would float would be a wing. Any part of the cabin area would have sunk by now. The problem with it being a wing is the total wing span (wing tip to wing tip) is only 119 feet. 20 feet of that total is fuselage which means each wing is a max of 50 feet. Of course the only way a wing could be floating is if the engine detached from the wing.
wing span is 199 feet 11 inches. So it's not inconceivable that the floating debris at 75 feet is a wing. Time will tell.

"The Malaysia Airlines flight that vanished nearly two weeks ago was already 12 minutes into its diverted course when the plane's co-pilot calmly told air traffic controllers that things were "all right," former FAA spokesman Scott Brenner said Tuesday on The Kelly File."
I've been seeing this all morning... before I believe it, I'd like to know exactly how they know this.
Strangely, all the reports on this new "fact" fail to explain how they made this determination or why it took 11 days to figure it out.

Color me skeptical...

Although, if this is true it makes it pretty clear that the disappearance was not an accident.

Another link http://news.iafrica.com/worldnews/908028.html
Need to be careful about not falling victim to intentionally vague words used to invoke emotional responses...

In this case "preprogrammed" very simply means that the pilot did not grab the yoke and turn the aircraft manually. Even the linked article later says that "preprogrammed" could mean.... (emphasis mine).
Rather than manually operating the plane's controls, whoever altered Flight 370's path typed seven or eight keystrokes into a computer situated between the captain and the co-pilot, according to officials.
If your ship was failing and you needed your hands free to deal with the crisis, the best way to start heading immediately back to land would be to type a few keystrokes into the autopilot and get back to fighting the fire (perhaps literally in this case). I read somewhere earlier (possibly the article I linked above?) that the heading chosen would have put the aircraft on a course towards a 13,000 foot runway on Langkawi.

Impossible to know for sure until more is known about actual events, but there's nothing inherently sinister about "preprogrammed" in this case, except for the medias intent to cause alarm where none is yet justified.

Re: Malaysia Airlines Flight Vanishes

I'm still placing my bets on some version of "mechanical/electrical/airframe failure/fire"

Here's another good hypothesis. Occam would be proud.
http://www.wired.com/autopia/2014/03/mh ... ical-fire/" onclick="window.open(this.href);return false;
The left turn is the key here. Zaharie Ahmad Shaw was a very experienced senior captain with 18,000 hours of flight time. We old pilots were drilled to know what is the closest airport of safe harbor while in cruise. Airports behind us, airports abeam us, and airports ahead of us. They’re always in our head. Always. If something happens, you don’t want to be thinking about what are you going to do–you already know what you are going to do. When I saw that left turn with a direct heading, I instinctively knew he was heading for an airport. He was taking a direct route to Palau Langkawi, a 13,000-foot airstrip with an approach over water and no obstacles. The captain did not turn back to Kuala Lampur because he knew he had 8,000-foot ridges to cross. He knew the terrain was friendlier toward Langkawi, which also was closer.

Take a look at this airport on Google Earth. The pilot did all the right things. He was confronted by some major event onboard that made him make an immediate turn to the closest, safest airport.

For me, the loss of transponders and communications makes perfect sense in a fire. And there most likely was an electrical fire. In the case of a fire, the first response is to pull the main busses and restore circuits one by one until you have isolated the bad one. If they pulled the busses, the plane would go silent. It probably was a serious event and the flight crew was occupied with controlling the plane and trying to fight the fire. Aviate, navigate, and lastly, communicate is the mantra in such situations.

:iagree: Makes a lot of sense.
Apparently this is a difficult thing to both "schedule" and to "execute".
How do you know where the other plane will be and exactly when?
How to you "catch up" to it in time to hide behind it when the timing needs to be just so and the difference between cruise speed and max speed isn't that great? (555Kts vs 590Kts).

I still believe it's likely not terrorism.
Either a cascading failure of equipment or possibly the pilot lost his mind.
